COLTER.

SPECIFICATION forming part of Letters Patent N 0. 749,591, dated January 12, 1904.

Application filed March 12, 1903. Serial No. 147,506. (No model.)

To all whom it may concern.-

Be it known that I, NORMAN W. TRAvIss, a citizen of the United States, residing at St. Thomas, in the county of Pembina and State of North Dakota, have invented new and useful Improvements in Colters, of which the following is a specification. V

This. invention relates to colters; and one of the objects thereof is to provide a yieldalolysupported colter wheel or disk adjustably secured with relation to the plow-beam.

Another object is to so construct the colter and its appurtenances that the disk or wheel will pass over any inequality or obstruction without affecting the plow-beam.

Another object is to provide means for permitting a limited lateral swing to be imparted to 131116 arms on which the wheel or disk is car: no

With these and other objectsin view the invention .consists in an adjustably-secured.

standard and a laterally-swinging yieldablysupported colter disk or wheel carried by the standard. I

The invention further consists in certain novel details of construction and combinations of parts to be referred to hereinafter and illustrated in the accompanying drawings, in which Figure 1 is a view in side elevation of a colter and the means for supporting it to the plow-beam. Fig.2 is a top plan View of the colter and securing-jaws. Fig. 3 is a bottom plan view of the same. Fig. 4. is a view in rear elevation of the colter-disk and supportinghead, part of the standard being broken away. Fig. 5 is a reverse face view of the ring and clamping-jaws for securing the standard to 'the plow-beam. Fig. 6 is a view,par tly in section and partly in elevation, of the arm andhead. Fig. 7 is afragmentary view, in side elevation, of a portion of thestandard and a depending bearing to which the head is secured. Fig. 8 is a view in elevation of one of the clamping-jaws which carry the standard. Fig. 9 is a top plan view thereof. Fig. 10 is a perspective view of the other clamping-jaw, and Fig. 11 is a top plan. View of the clamping-jaw.

The reference-numeral 1 designates a standard or stem which is in the form of an eloncarried by the jaw 5. The jaw 5 is illustrated in detail in Figs. 8 and 9, audit comprises a plate 10, formed with an approximately D- shaped loop 11 integral with the plate and strengthened by an intermediate flange or rib 12, whichis intersected by a perforation l3, threaded internally to receive the threaded end of the lever 7. Intermediate the ends of the plate 10 and between the walls of the loop 11. are oppositely-located cut-out portions 14: and 15 in the respective edges of the plate. These cut-out portions are for the reception of stops or projections on one side of the second jaw, tobe referred to hereinafter.

16 designates a ring formed with diametrically oppositely disposed ears or lugs 17 and 18, through which suitable fastening devices can be passed to secure the ring in the side of the plow-beam. The ring 16 is formed with a notched or toothed flange 19, projecting from one of the edges thereof, so as to leave a space between the jaws for the reception of the opposite endsof the platelO. The jaw of which the plate forms a part is held in lockedposition with relation to the ring by a second clamping-jaw, (designated by the referencenumeral 19), This jaw is in the form of an approximately rectangular block, with a concaved longitudinally-arranged groove 20 coinciding with the curved portion of the loop 11, so that the concaved portion of the block and the loop will. firmly embrace the cylindrical standard 1-. The projections 21 and 22, which are parallel with each otherand extend from one side of the jaw 6oppositeto the concaved groove 20, are for the purpose of preventing displacement of the jaws 5 and 6. By reference to Fig. 5 it will be noticed that these projections interlock with the cut-out portions in the plate 10, and when the standard 1 is in proper relative position, as shown in Fig. 1, the jaws will be held against displacement cide with the notches formed in the flange 19 of the ring 16, and the spaces between the teeth on "the jaw 6 coincide with the teeth on the flange of the ring 16, so that the teeth and spaces in the jaw will interlock with those formed in the ring, and when the lever 7 isadjusted so as to tighten several parts the standard 1 can be rigidly secured in any adjusted position, as occasion may demand. The head carried by the lower extremity of the standard 1 comprises two disks 25 and 26, connected by a concentric tubular bearing 27, the ends of which extend slightly beyond the outer faces of the disks to form supports 28 for the coiled tension-spring 29, to be more specifically referred to hereinafter. The rear portions of the disks are connected by a vertically-disposed tubular barrel 30, Which fits over the depending stub-shaft 3 and is secured thereto by a pin 31, which passes through the barrel, so that the end thereof rests in the arcuate groove 4, the ends of the groove forming stops to limit the lateral movement or swing of the head. This head supports the arms 32 and 33, which are formed with inwardly-disposed tubular shafts 34,.resting within the tubular bearing 27. These shafts 34 are revolubly mounted within the bearing 27 by a bolt or rod 35, extending concentrically through the bearing and through the shafts. The arms are yieldably supported with relation to the head by the coiled springs 29, which surround the ends of the tubular bearing 27 and have diverging oppositely-disposed terminals 36 and 37 in engagement with the flanges 38 and 39, carried by the arms and head, respectively. This arrangement will permit the arms to be normally spring-pressed, so as to hold them in an approximately horizontal position; but when the colter wheel or disk comes into contact with an inequality of the ground the resistance will be sufficient to raise the disk, permitting it to pass over the obstruction without affecting the remaining portion of the supporting mechanism. The downward movement of the arms will be limited by a shoulder 40, formed on the flange 38 of one of the arms to be engaged by an abutting end of one of the flanges 39, formed on the head. The upward movement of the disk, however, will be unrestricted except by the resistance of the springs.

By operating the lever 7 to loosen the jaws 5 and 6 they can be swung on an arc in either direction to adjust the standard 1 in any determined relation to the ring. It will also be obvious that a slight lateral play or movement can be had by the arms and disk as the colter travels over the ground.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described the invention, what is claimed'as new 1s- 1. The combination with a rotatable standard, of pivoted arms carried by the lower extremity of the standard, and tension-springs engaging the portions of the said arms adjacent to the standard whereby spring-pressure will be exerted in a downward direction on the arms.

2. The combination with a standard; of a head mounted on the lower portion of the standard, a tubular bearing carried by the head, pivoted arms carried by the bearing and supporting a colter-disk, and tension-springs coiled on the respective ends of the bearing with oppositely-disposed ends bearing against the arms and the head, whereby spring-pressure will be exerted in a downward direction on the arms.

3. The combination with a ring to be secured to a support and being formed with an alternate series of teeth and intervening spaces; of a pair of clampingjaws, one of which comprisesa plate extending beyond the edge of the ring, and an intermediate loop formed on the plate, a colter-standard projecting through the loop, a second jaw disposed within the loop and engaging the standard, and teeth on the jaw for engaging the in tervening spaces on the ring, and means for securing the jaws, ring and standard in interlocking engagement.

.4. The combination with a ring formed with a concentric flange having a central opening; of a colter-standard and jaws for securing the standard to the ring, one of which comprises a plate overlapping the edge of the face-flange and having oppositely-disposed notches in the jaws thereof, a second jaw bearing against the opposite side of the face-flange, and means on the second jaw for engagement with the notches in the first jaw so that both jaws can be adjustably secured to the ring for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

NORMAN W. TRAVISS.
